    摘要: A data processing apparatus includes two data transmission paths formed likewise in a loop fashion. These data transmission paths include a plurality of latch registers connected in a cascade fashion respectively and are constituted as a so-called self-running type shift register wherein each data word constituting a data packet is shifted in sequence provided that a pre-stage register is vacant. Data packets are transmitted in the directions reverse to each other on the two loop-shaped data transmission paths an identification data included in each data packet being transmitted is detected in a section defined as a data packet pair detecting section. The detected identification data are compared in a comparing circuit and, one new data packet is produced from the two data packets in a manner that a data packet is joined from one data transmission path to the other data transmission path.

    摘要: A data transmission system comprises an input data transmission line (1), an output data transmission line (4), a branching data transmission line (5) and a jointing data transmission line (7) formed respectively by asynchronous free-running shift registers using a plurality of data latches (101 to 106, 401 & 402, 501 & 502, 701 & 702) and, C elements (111 to 116, 411 & 412, 511 & 512, 711 & 712) respectively. A branching control circuit 3 supplies data to be branched to the branching data transmission line (5) in response to the decision by a branching decision circuit (2) as to the fact that the data to be branched is transmitted on the input data transmission line (1). A jointing control circuit (6) supplies data to be joined to the output data transmission line (4) in response to the decision by an empty buffer verifier (8) as to the nonexistence of data in the input data transmission line (1) and the output data transmission line (4) when the data to be jointed is transmitted on the jointing data transmission line (7). Thus, the data transmission system has branching and jointing functions and if it is used as a constituent of a network, data can be transmitted among asynchronous systems.

    摘要: In an information processor, input interface units (161, 162) are connected to one ring data bus (191) through jointing units (201, 202) and data processing units (181 and 185) are connected to the ring data bus (191) through jointing units (203 through 206) and branching units (221 through 224). Data processing units (183 through 187) are connected to the other ring data bus (192) through jointing units (207 through 210) and branching units (225 through 228) and output interface units (171, 172) are connected to the other ring data bus (192) through branching units (229, 230). The ring data buses (191, 192) propagate the respective in data through the input interface units (161, 162) while storing such data, and processing the data in any of the data processing units to provide outputs to any of the output interface units (171, 172). Thus, since the data is transmitted through the ring data buses ( 191, 192) while being held in the data buses, there is no necessity to provide a memory for temporarily storing the data in each data processing unit. In addition, for a large scale integration of a system, it is easy to integrate each unit in a high density.

    摘要: A data processing apparatus includes a self-running type shift register and this shift register includes a plurality of latch registers arranged in a cascade fashion. The latch register latches a data packet on a word basis. In each latch register, a coincidence element is disposed in association therewith and these coincidence elements allow transfer of data from a post-stage latch register provided that a pre-stage latch register is vacant. A data processing element is installed between two latch registers and the data processing element processes operand data from either or both of the two latch register in response to the kind of processing shown by an operation code comprised in the preceding word. The result of processing is transferred to the pre-stage latch register when the pre-stage latch register is placed in the vacant state under control of the coincidence element.
